short space. >> within a city you can have four different temperatures. san francisco one side of the city, ocean beach could be freezing cold with fog in the summertime. you get out towards the embarcadero area and it could be beautiful and sunny. >> trying to find that nuance and glitch in the huge atmosphere that is going to make our weather a little bit different today because we live in these microclimates, it's going going to affect everybody the same way. the weather here it's completely different than any other place in the united states. >> you go out to kansas, you may have a degree temperature difference. that is how most areas are. >> it's one of the main reasons that we have such diverse weather conditions from location to location. we've got a higher terrain in the mountains and hills that help determine wind flow. that shields certain areas from
rainfall or from the warming effect of the sun. we've got the ocean and marine influence which generally keeps locations near the ocean cool. >> you look at the south bay, you have mountains on one side and mountains on the other side. there is a reason they get the least amount have rain, it's called rain fade. it goes up the santa cruz mountains, that creates the clouds. the santa cruz mountains rains like crazy down there. conversely, when it comes over and sinks into the valley, it stabilizes the atmosphere and you can get two to three inches of rain and san jose will get couple hundredths or a tenth. so the greatest population is getting the least amount rain. there are so many different ways you can save water. put a bucket in the shower while the water is warming up. waterhe bucke your plants with that.

they know that it is changing. >> certainly on the global scale you have these temperatures rising over the past few decades. there is no question about it. the numbers are there. there are observations to show these things are occurringhe >> one of the things temperatures and rainfall and climate change, possible rises in tide levels. when you have all this water getting warmer. so a a along the predictions for temperature and rainfall, we have predictions for climate change how much at sea level is going to rise. something ingin the order of the next 90 years between now and 2100 of sea level rising something like two feet, maybe up to three feet. >> the way we live our lives will change. you see it when we do the news

technique that allows the weather person to stand in front of the green screen and blue screen but there nothing behind us but the images you see are superimposed and transmitted to your tv screen. >> it's been the advent of the computer that has made our job better in the sense we are forecasting better. in the sense we can see things longer out but raised expectations. especially living out in silicon valley, everybody expects, aren't they perfect? no, not really, but they are getting better. weather computer models that have algorithms, you couldn't do it by hand. it takes three hours with a super computer to crunch a forecast. you try do it by hand and you really couldn't. they also helped us display what we know in a way that makes
sense to everybody at home. >> live doppler 7-hd is a critical part of our story telling, our weather forecasting where is the rain now, where is ioing. it can pick up moisture in different layers of the atmosphere. >> basically satellite technology and radar technology have given us the ability to provide such accurate forecasts to go from three-day forecasts to five-day forecasts to seven-daysts. >> doppler radar is a key tool in the arsenal of meteorologists. not just us but the media the people here at kgo, their doppler radar is very important tool. >> i saw something on our doppler that indicated there was a real strong cell, potential where it looked a little concerning. this isn't something we see very often. it was severe thunderstorm. seconds later, something came up
on the wires, severe thunderstorm warning and tornado warning has been issued for santa clara county including the city of morgan hill. >> when you see a tornado in live doppler radar, you can see the winds moving in opposite directions. the old radars you had to look for a hook echo, you are looking at precipitation shield as a whole. but by that time it's got a tornado on the ground and you missed the lead time to warn people. >> one of the most important parts of my job is to warn the public of up coming danger. >> our system is so advanced and so sensitive it does it better than any other system out there. ♪ >> still to come, what role can you play in forecasting? see how social media is changing the way we stay informed about bay area weather. ys of walking to give a breast cancer survivor a lifetime-- that's definitely a fair trade.
